2016 Nissan Rogue - Repeated headlight issues

replaced passenger headlight 4 times now due to headlight holding water (not condensation). Now its doing this all again. Nissan of Melbourne Florida says they don’t know why its happening, UGH

There must be a path for the water to get into the headlight fixture. It’s not getting in by magic. Rain water, flood water, splashing when driving through puddles, car washes, something is sourcing the water. Suggest to ask the dealership or your own inde shop to remove the headlight ass’y and bench-inspect under good lighting/magnifying glass… Repair any place a leak into the fixture could occur, or replace the entire ass’y if necessary, then reinstall using any the sealants required per the shop manual installation procedure. This might be expensive in labor hours, so ask for an estimate first.

Unnecessary, a replacement headlight should have a 12 month/12,000 mile warranty. If the replacement headlamp is leaking in water, the headlamp should be replaced.
